Hi,

Create a server action

<record id="model_product_template_inherit" model="ir.actions.server">

    <field name="name">Wizard</field>

    <field name="model_id" ref=product.model_product_template"/>

    <field name="binding_view_types">form</field>

    <field name="state">code</field>

    <field name="code">action=recor.open_wizard()</field>

</record>

Then create a function on the corresponding model and return an action here mentioning the model and view_id.

def open_wizard(self):
    return {
        'name': 'Wizard',
        'type': 'ir.actions.act_window',
        'view_mode': 'form',
        "view_type": "form",
        'res_model': 'product.generation.wizard',
        'target': 'new',
        'view_id': self.env.ref
        ('product_generation.product_generation_wizard_form').id,
        'context': {'active_id': self.id},
    }
